N2 - In this research, the composition and proportion of surrogates were first determined according to the composition of the petrochemical and renewable fuels. Then, the CHBR model in CHEMKIN-Pro software was used to verify the ignition delay time of HRJ, JP-5, and HRD. The differences in the ignition delay time of the fuels under an equivalence ratio of 1.0, different pressures (8, 11, 30 bar), and a pressure of 20 bar, and different equivalence ratios (0.5, 1.0, 1.5) are discussed. Among the three types of aviation fuel, the ignition delay time of HRJ in the low-temperature range was the shortest, while that of JP-5 was the longest. The average ignition delay time of HRJ in the low-temperature range under different equivalence ratios and pressures was approximately 59% and 57% lower than that of JP-5, respectively. On the other hand, the average ignition delay time of HRD in the low-temperature range at different equivalence ratios and pressures was 45% and 55% lower than that of petrochemical diesel, respectively. The ignition delay time of all of the fuels was shorter when the pressure was increased.
